20-kV qBSE image of distal third metacarpal bone from Thoroughbred racehorse from the Bristol treadmill training study, showing infilling of prior marrow space with new bone, without prior resorption and with new woven bone strands in centre of prior marrow space. Tissue processing and super drying in SEM caused cracking at the junctions of new with older trabecular bone tissue. Asterisks mark poorly mineralized join lines with older lamellar bone. M = marrow space. Field width, 900 μm.
